This invention relates to new and useful improvements in drilling machines and more particularly to means whereby to retaln objectsto be drilled, in their proper positions 5 while being drilled. One of the objects of the present invention isthe provision of a drilling device which can be minutely adjusted so, I that the devicesto'be drilledwillbe properly positioned with respect to the drill so that the drilling can be carried'out'to the proper proportion. a I

' Another'object ofjthe invention is the provision of a device ofthe above character wherein the articles to be drilled are posi *tionfefd" in a movable carrier which may be manuallyor otherwise propelledto consecutivefly' position the articles beneath the drill andfdispense said articles after being drilled. A'further object of the invention is the provision of a device'of the above character wherein the article carrier'can be made a singlepiece or in several pieceswith each pieceprovided with an article recelv ng seat.

With the aboveand other objects in view I the'invention consists in the novel features of construction, the combination and arrangement of parts hereinafter more fully set forth, pointed out in the claim and shown in the accompanying drawings, in which I Figure 1 Visa side elevation of a drilling device constructed in accordance with my invention Figure 2 is a top plan view. I 1 Figure 3 is section on the line 33 of Figure 4 is a-top plan view with the rotatable carrier removed, illustrating the removablebottom plate. Figurefi is a section on the line 55 of Figure 4.

Figure 6 is a top plan view of a one'piece carrier plate.

Figure 7 is an edge view of the plate illus In the accompanying drawings it will be noted that the entire device is supported u on a hollow base or standard 1, the lower en of which is formed with an annular flange 2, formed with openings 3 to receive any 'suita- 5 ble type of fastening members to secure the base to a solid foundation. The upper end of the standard is also formed withan annular outstanding flange 4. which forms a suitable base or support'for the other parts of the' device. Mounted upon the standard 1 and removably secured thereto by means of the screw bolts 5 is thebottoin plate 6,' which isformed with a groove 7, having its ends terminating into atransverse opening 8 through which the finished articles are dispensed. The perimeter of the bottom plate 61is formed with an annular rib 9 forming a bearing surface upon which the circular carrier ring 10 is rotatably mounted. The lower edge of thering 10 is r provided with an annular rib 11 which'pro- :jects inwardly and which engages beneath the rib 9 to retain the ring '10 against riding up wardly on the rib 9.

Threaded into the outer ring 10 and engaging the upper face of the rib 9 is a retaining ring 12 to which the carrier sectors 13 are secured by means of the set screws 14. The outer edgeof each sector plate is formed with a lip 15 which projects over the ring12 and is formed withan arcuate slot 16to,receive its respective set screw 14:, so'thateachsector can beindependently adj usted and retained in its proper adjusted position. The innerend of each sector is formed with a reduced part which is pivotally connected to theffla'nged head ofa button like member 17, means of the screw 18, said screw operating in an arcu ate groove 19 and bearing against the sector to retain the inner end of the sector in its proper adjusted position. q

Each sector 13 is formed with an article receiving seat or openingQO, said seats or openings being of different shapes or of such shape as desired to accommodate articles of difierent shapes. These seats or openings are preferably positioned in line or abovethe groove 7, so that thewaste material from the drilling will be'received by them. In order 'to properly position the articles to be drilled beneath the drill and retain them in this position, the ring 12. is formed with a circular series of conical openings 21, any one of which is adapted to receive the conical end 22 of the adjustable retaining member 23. The

retaining member 23 is threaded and adjusta- I bly mounted in thesupporting sleeve 24 on the upper end of the bracket 25. This bracket 25 is removably mounted upon the standard 1 by means otthescrew bolts 26,"the lower end of saidbracket being seated in a suitable recess formed in one side of the standard. A removable screw bolt 26 i's'also extended through the bracket and engaged" with the bottom plate 6 The drill holder 27 is adjustably supported upon a bracket 28, which is removably attached to-the standard 1 and upon'which is mounted'an adjustablestandard or arm 29, The standard or-arm is'formedwith'a longitudinal slot 30 which receives the set screws 31 on the bracket 28,. whereby the arm 29 can be; raised or lowered and retained in its adjusted position. The holder this member maybe readily adjusted to pros jectthe end 22 into any one of the openings 21,o r retract the same therefrom.

V ;The solid or'one piece article retaining plate 37 is formed with circumferentially spaced arcuate slots 38 toreceive the'set screws-1a; to retain the plate SK i-n various moved under the drill and the article in the adjusted positions. 'The -platefl37 is-also formed upon its sloped peripheral edge with a series of graduations 39, which areused in connection (I withgthe indicator 4 0 when min ute adjustments arerequired. The plate is also tormedwith article receiving seats or openings 41, which are so positioned that they will be disposed over the groove 7 when the plate37-isin use rFr-om the above it willtbev apparent l 1n using the device as showninFigure '2,

the farthermost seat or opening 20 i'sready to. receivean article to .bey drilled while the article in-theopening at the rig-ht has been lowermost opening is'about'to bemoved over the opening 8 to dispense the latteriarticle. After one article has been drilled thememtically or laterally in accordance with the H work and is so constructed that the same may. be retained in various adjusted positions.

It will be noted that the waste material from the drilling will drop down into the groove-7 from. where it may: be readily cleaned out. It will bereadily apparent that 1 the sectors 13 may be readily adjusted through the medium of the set screws 14 and '18 so thatrdrillingimay be'done in different parts of the articlesheld in the seats or open ings 20. As'statedheretofore, the one piece '37 can be used in place of the sectors 13 it so desired and mlnute ad ustments can be 39 andthe indicator tOl K obtainedthrough the useofthe graduations W'hile'l have shown andj'fdescrihedthe preferred ,torin of. my I device. it will be ap-j parent that various changes and alterations may be 'carried'out, when putting thesinvem tion into practice'without departing from the spirit of the iinvf ention or the scope of the ap: pended claim. m ll 7 I claim as inventionz '7, 1

In a drilling jig a'base member,'a removable bottom plate secured to the base, said Y plate having a transverseopening; there be ing acircular groove in the upper face of the plate communicating; with the opening, a rotatable member fernbracingjthe outer fipe;
